Abstract

In accordance with the implementation of the Positive List System (PLS), the proper usage of pesticides is now being enforced. It is assumed that unregistered pesticides are being used on agroforestry products due to the low number of registered pesticides in the agricultural industry. In this study, pesticide and heavy metal residues were investigated in 13 types of products to determine the status of usage. The levels (%) of pesticides detected in Pimpinella beachscape, Platycodon grandiflorum, Codonopsis lancekolate, Artemisia dubia, Angelica gigas, Pyrus pyrifolia, and Punica granatum were 40.0, 20.0, 26.7, 13.3, 56.3, 57.1, 33.3, 26.7, 66.7, and 46.7%, respectively, while, those in Petridium aquilinum, Disoscorea batata and Senna tora were zero. Heavy metals (Pb, Cd) were detected only from P. grandisflorum and A. dubia. The pesticide usage and registration data by agroforestry product obtained in the study will be useful in the future for ensuring the safety of domestic agroforestry products.

농약허용물질목록관린제도의 시행에 따라, 농약의 안전사용이 더욱 중시되었다. 산림식용자원(임산물)은 소규모 재배 등의 이유로 등록된 농약의 수가 적어, 등록되지 않은 농약의 사용이 예상된다. 이에, 본 연구는 임산물에 대한 농약사용실태를 파악하고자, 산림식용자원 13종에 대한 농약 및 중금속 잔류실태조사를 하였다. 산나물류 조사 시료인 고사리, 참나물, 도라지, 더덕에 대하여 조사 시료의 0%, 40.0%, 20.0, 26.7%에서 농약이 검출되었고, 약초류인 참쑥, 당귀, 마는 13.3%, 56.3%, 0%의 농약 사용이 확인되었다. 과실류 조사 시료인 석류, 복분자딸기, 다래, 머루, 돌배, 결명자에서는 조사 시료의 57.1%, 33.3%, 26.7%, 66.7%, 46.7%, 0%에서 농약이 검출되었다. 중금속(납, 카드뮴)은 도라지와 참쑥에서만 검출되었다. 연구에서 얻은 임산물별 사용농약에 대한 정보는 병해충 방제를 위한 사용현황을 확인하여, 추후 농약등록을 위한 정보를 제공하므로 국내 임산물의 안전성 확인을 위한 자료로 활용할 가치가 있을 것이다.
